Mad Hatter: Ah thank goodness! Those are the things that upset me!
March Hare: See all the trouble you started?

Cheshire Cat: If I were looking for a white rabbit, I'd ask the Mad Hatter.
Alice: The Mad Hatter? Oh, no no no…
Cheshire Cat: Or, you could ask the March Hare, in that direction.
Alice: Oh, thank you. I think I'll see him…
Cheshire Cat: Of course, he's mad, too.
Alice: But I don't want to go among mad people.
Cheshire Cat: Oh, you can't help that. Most everyone's mad here.

Cheshire Cat: You may have noticed that I'm not all there myself.
